Golf IV / Jetta IV :: Buzzing / Hissing Noise At Certain Speeds / RPMs / Loads
I have a 2002 Jetta GLS 2.0 4-speed automatic, 151,xxx miles... I have only owned it a couple of thousand miles, so I can't offer much on what is "normal"...
The issue I am having is as follows: I sometimes get a strange buzzing/hissing noise that sounds like it is coming from the engine compartment ~45 degrees to my right while driving. It's very hard to describe - the best I can say is it sounds a bit like a little plastic gear is spinning/grinding at high rpms, yielding a buzzing noise, and there is a hissing-like sound as a backdrop.
The sound happens only occasionally (but seems to be happening much more frequently, which is worrisome). I have heard the sound in different driving scenarios, so I can't say "it only happens when...". However, it DOES seem to be sensitive to throttle and driving conditions in some way. I have heard it while a shift is taking place, I have heard it under load on a long incline, and I tend to hear it right around 60mph. Interestingly, in the 60mph example, can make the sound go away by accelerating past 65, or by decelerating down to ~50... it seems like there is some kind of transition taking place at 60 that fosters the sound?
The transmission is generally functional - I had the fluid changed right after buying it (with the correct fluid), and it generally shifts ok. It does have some of the quirky behavior the transmission is known for: occasionally hesitates to go from R to D, sometimes shifts while driving are less subtle than they should be. But I'd say as a whole it operates as a 4-speed transmission would be expected to.
However, since this strange noise is getting worse, and seems to be related to shifts/load/andor speed in some way... I am worried about trans health. What to check? Because it is intermittent, and doesn't exist at idle and rarely appears when going around the block good luck getting a mechanic to observe it...
Golf V R32 :: Heavier Gauge Pos Bat Cable
Replacing the factory pos cable from the alt to the bat in the rear yet? if you have what is the path and was it a pain to do? I have not had the chance to get the car on a lift yet to check and don't know even if it needs to be on a lift to do.

I have a MK4 Golf 2003 1.9Tdi PD100 , the problem is that the engine seems to miss when idling , so the question really is how can I tell which cylinder is missing , it seems to do it every 10 seconds or so and the engine shakes slightly at the time as if it were missing ! .
I suppose it would be easier if the cylinder was missing all the time , then maybe I could crack open a line at a time ! , but can you do that on a PD engine !
Golf IV / Jetta IV :: While Driving Air Comes From Hose - Run Roughly And Miss
So I had a hose come apart that is located under the intake manifold on my 1.8t. It's some type of air hose because I can hear and feel the air coming out when the car is running, and it's also making my car run rough and miss, mostly at idle.

Almost a month of driving it and my 1st to 2nd shifts are hit or miss in a way. Because they'll be nice and smooth one day but the next, I end up with revs that hang. Like I shift up at 3k and they just stay there for a good second and then drop.

i am the original owner of a 2004 Prius with about 120k miles. I am considering replacing the struts even though they aren't horrible. I figure I won't have the car more than 240k miles so might as well get the struts on earlier rather than later so I enjoy them as long as possible.

My voltmeter (91 Explorer) bounces with loads, i.e. when sitting at a stop light with the brake lights and turn signal on.
Revving the engine up doesn't seem to work. What does this indicate? Bad battery? Bad alternator or voltage regulator?
Prius (2004-09) :: 2007 - Stubborn TPMS Sensor After Loads
My 2007 Prius has a stubborn TPMS light. This started about a week and a half ago after I made a few trips from my house which sold to my new apartment. I had the car loaded up with stuff in each of the four trips and maybe had a lot of weight.
I checked the tire pressure after the 3rd trip and it looked fine on all of them. I set them to 35 psi and made one more trip with heavy-ish stuff. I did not check the tire pressure after that last trip but I tried resetting the TPMS light.
I press my foot on the brake pedal and hit the power button twice and then I held the Set button until I saw the TPMS pattern change to three blinks and then it stops. It then continues blinking for the 1 minute duration and stays solid. I tried this a couple of times and waited 3 minutes or so after doing it to see if it made any difference.
Am I likely not trying to reset correctly? I also have techstream on a cd and the tool and a laptop but am not sure if I should set that up and then try to debug using that tool?
Malibu :: 1997 Chevy Misfire At Random Times And When Under Heavy Loads
I have a 97 Chevy Malibu V6 3.1L with 92k miles on it, a couple weeks ago i started getting a misfire issue. The car would start to misfire when under heavy load such as accelerating up a hill. The local auto parts store diagnosed it with code P0302(cylinder #2 misfire). I started by replacing all of my spark plugs(ACDelco Platnum) and wires. This seemed to fix the issue for a day or so, after that the misfire worsened. I would misfire at random times and when under heavy loads. This caused my transmission to keep shifting up and down followed by the all to familiar hot/melted plastic smell of overheated transmission fluid. This continued on for a few days as it got worse.
The car than started to misfire heavily all the time. I took the car to another auto store and it pulled up codes for Random/multiple misfire. I then took my car to a mechanic for a full diagnostic, their computer said their was a misfire on cylinder #1, as-well as a bad spark plug wire on #1( He found this by getting shocked while wiggling the wires on the coil pack) and told me to replace the bad wire. I replaced all wires again and the problem remained. i took it back up for re-diagnosis and they then said it was a bad coil pack. I replaced the coil packs and the problem still remains.

View 10 RepliesHonda - Accord :: 2008 - SRS Light On / Loads Of Dirt Dust Behind Dash And Panels
2008 honda accord coupe ex-l
So, I assisted my sister in finding my nephew a used car and everything looked great on the surface as well as mechanical. We get the car home and the SRS light comes on.. I started digging into why and find there is dirt dust all behind the dash and side panels around airbags in back and pretty much everywhere below the surface.
Digging into the service records I see they did have to replace a fender liner which might have been a port of entry for all the dirt and dust. Apparently the young driver was putting in mileage on dry dirt roads without a fender liner.
I did caution against buying this car previously, even before looking at it, because it was a teenage driver, there was a minor wreck into driver's door and repairs had to be made for him running up on a curb as well. But in their desperation for a car.. they asked me to check out the mechanics of it.. i did.. they looked good.. but I missed all this dirt dust and now i feel bad.
Anyways, how to go about cleaning out all this dirt dust behind the dash, and panels of the car? I worried if I leave it there, he will experience additional expensive electronic issues.
Was thinking of taking off some side panels and dash off, and using a vacuum with a brush head to try and get it.. I could use compressed air.. but perhaps that may be potentially harmful to other electronics and connections?
As for the SRS light, i was able to count the light flashes in dash to get code 8-3 off of the flashing SRS light and a 7-1 off the ABS light. Referencing those: "Internal Failure of SRS unit".

2002 F-250 tries to die when I shift from drive to reverse. Usually first 10-15 minutes after starting. After it has gone a few miles I haven't noticed it. Seems to be getting worse but just really started a few weeks ago. I don't drive it everyday so it has been a while.
View 2 RepliesFord F-150 - 1997-2003 :: Lack Of Power Showing Up Pulling Loads At Highway Speed
My 2000, F150, 4X4, 4.6V8, five speed manual idles great and sounds great and throwing no codes. It doesn't have a lot of zip, but it really never has, at least since I bought it at almost 60K miles.
I've never towed much of anything with it until recently. I started towing a 6 1/2' X 10' trailer with a 1,600 pound side by side or a 1,300 pound mower with a large grass collector. Both of these loads have lots of wind resistance.
The lack of power is REALLY showing up pulling these loads at highway speed. Sometimes, even on pretty flat ground, the cruise control will hold the throttle on the floor at 60 or 65 MPH and it can't pick up speed.
I have maintained the truck well, but there is something amiss. It is due a fuel filter, so I will change that. I've never replaced the O2 sensors, so I'm considering replacing the front ones.
I am thinking about using a vacuum gauge to see if I can detect plugged cats. As I recall, there are two on each bank. I have a scanner, so I was thinking about monitoring front and rear O2 sensors and see if I can get the 100 degree difference that indicates a properly functioning converter.
I'm thinking of cleaning the throttle body.
Something else that is odd about this truck. Being a stick shift, it does not want to go all the way back down to idle speed unless the vehicle is stopped. For illustration of what I'm saying, you can kick the transmission in neutral and coast, and it will stay above idle speed until the vehicle stops, THEN it will idle down normally. I have always thought that this might be because so few manual transmission trucks were built that this is something in the chip for an automatic that they didn't take out for the manual.
